prosumers (both producers and consumers) on the Stellar network, facilitating secure peer-to-peer energy transactions with real-time settlement. + +## Overview + +This contract enables prosumers to: +- Create energy sharing agreements directly with other prosumers +- Record energy delivery with smart meter verification +- Execute secure payments using Stellar tokens +- Track complete transaction history +- Handle dispute resolution mechanisms + +## Features + +### Core Functionality +- **Prosumer Registration**: Single registration for participants who can both produce and consume energy +- **Energy Agreements**: Create bilateral agreements specifying quantity, price, and delivery terms +- **Meter Verification**: Record energy delivery with meter reading validation +- **Secure Settlement**: Automatic payment processing using Stellar tokens +- **Transaction History**: Complete audit trail of all energy sharing activities + +### Energy Sharing Features +- **Direct P2P Trading**: No intermediary marketplace required +- **Flexible Agreements**: Custom terms for each energy sharing arrangement +- **Real-time Settlement**: Immediate payment upon energy delivery verification +- **Dispute Handling**: Built-in dispute mechanisms for delivery discrepancies +- **Deadline Management**: Time-bound agreements with expiration handling + +## Contract Structure + +```
